Smart discovery of wireless receivers

ABSTRACT

The present disclosure discloses automated discovery of and seamless connection to wireless receivers for mirroring, extending, and/or projecting images, audio, and/or video from a computing device to the wireless receivers. A smart discovery program discovers a specific wireless receiver that matches a location for a meeting and provides the user with an option to wirelessly connect to the matching receiver during the meeting. The smart discovery program may also use a current location of the computing device to provide a user with a list relevant wireless receivers. Relevant receivers may include those receivers that are both available and located near the computing device. When a computing device connects to a wireless receiver, it may store the receiver ID for the connected receiver in a local receiver log so that the computing device may use this information to connect to the same receiver at a later time.

BACKGROUND

There are several technologies that allow a user to share images, video,and audio from a computing device to a larger screen without wires.

For example, Miracast is a wireless display standard designed formirroring, extending, and projecting from a smartphone, tablet, or PC'sscreen to a display device (e.g., a television, monitor, or projector)without requiring any physical cables. Miracast allows devices todiscover each other, connect to each other, and mirror, extend, andproject the contents of their screens wirelessly. Miracast is designedto be a cross-platform standard.

As standard, Miracast is defined over Wi-Fi Direct. When using typicalMiracast over Wi-Fi Direct, a user who wishes to connect to a Miracastreceiver will be shown a list of current receivers within the range ofWi-Fi Direct. However, there is no way for a user to distinguish amongthese wireless receivers unless the receivers have been named using acontext-based scheme such as a naming convention that relates tophysical location. For example, when a user wishes to connect to awireless receiver during a meeting there may be no way to determinewhich receiver to choose unless the receiver ID matches the name of themeeting room or the receiver ID is physically marked on the receiver. Inthe first instance, naming schemes based on location are difficult tomaintain when receivers are moved or removed and as new receivers areadded to the system. Even when the receiver is physically labeled, theuser must still manually compare the receiver ID on the receiver in themeeting room with the list of in-range receivers shown on the device.Further, users must go through this exercise every time they attend ameeting in that room. As such, there is a need for an improved way toautomatically discover the correct wireless receiver to use for ameeting.

This problem is compounded by the risk in inadvertent disclosure ofrestricted material. For example, connecting to the wrong receiver mayrisk exposure of confidential, private, or otherwise restrictedinformation to unintended recipients and/or at unintended locations.

Miracast over Infrastructure is an extension of the Miracast standardthat allows for use of Miracast over a network, such as an enterprisenetwork. With Miracast over Infrastructure, discovery of wirelessreceivers occurs differently. Discovery uses mDNS broadcasts that willfind all receivers on the local logical subnet with the Miracast sender.However, that logical subnet may span any number of locations that arenot within physical proximity of the Miracast sender. As such, a userwho wishes to connect to a Miracast receiver may receive too manyavailable receivers to be able to efficiently and correctly choose theright one. As such, there is a need for an improved way to discover thecorrect or best available wireless receiver using Miracast overInfrastructure.

Miracast over Infrastructure also allows for user devices to connect toany Miracast receiver within the local network including receivers thatare part of a different logical subnet than the user device. However,user devices are not capable of discovering receivers located in adifferent logical subnet even if the device has connected to aparticular receiver before. Therefore, there is a need for an improvedway for computing devices to connect to Miracast receivers in differentsubnets.

It is with respect to these and other considerations that examples havebeen made. Also, although relatively specific problems have beendiscussed, it should be understood that the examples should not belimited to solving the specific problems identified in the background.

SUMMARY

This Summary is provided to introduce a selection of concepts in asimplified form that are further described below in the DetailedDescription. This Summary is not intended to identify key features oressential features of the claimed subject matter, nor is it intended tobe used to limit the scope of the claimed subject matter. Additionalaspects, features, and/or advantages of examples will be set forth inpart in the description which follows and, in part, will be apparentfrom the description, or may be learned by practice of the disclosure.

Examples of the present disclosure provide for automated discovery ofand seamless connection to wireless receivers for mirroring, extending,and projecting images, video, and/or audio from a computing device tothe wireless receivers. A smart discovery program (e.g., an applicationor service/daemon) discovers a specific wireless receiver that matches alocation for a meeting and provides the user with an option towirelessly connect to the matching receiver during the meeting. Thesmart discovery program may temporarily store the matching receiver in alocal receiver log on the client device so that the user may easilyconnect to the matching receiver at any time during the duration of themeeting. A server may maintain a receiver log that includes entriesmatching meeting locations to wireless receivers. When the smart meetingapplication detects that a meeting has started or is about to start, itmay send a request to the server to identify a matching receiver for themeeting.

In aspects of the present invention, a computing device is capable ofconnecting to a plurality of wireless receivers and the smart discoveryapplication or service/daemon uses a current location of the computingdevice to provide a user with a list relevant wireless receivers.Relevant receivers may include those receivers that are both availableand located near the computing device.

When a user requests to connect the computing device to a wirelessreceiver, the smart application or service/daemon may determine whetheror not the user has an appointment at the time of the request. If thereis an ongoing appointment, the system may identify a specific wirelessreceiver that matches the location of the meeting and prompt the user toconnect to the matching wireless receiver. If the user does not have anongoing or imminent meeting, the system may use a current location ofthe computing device to provide the user with a list of relevantwireless receivers.

When a computing device connects to a wireless receiver, it may storethe receiver ID for the connected receiver in a local receiver log sothat the computing device may use this information to connect to thesame receiver at a later time. The computing device may also send thereceiver ID and its associated location, if available, to a server forstorage in a receiver log. This server receiver log may be used toprovide a user with a matching receiver for a meeting at a later time.

In aspects of the present disclosure, the computing devices and thewireless receivers are Miracast-compatible and may connect to each otherusing a Miracast protocol.

DETAILED DESCRIPTION

Various aspects are described more fully below with reference to theaccompanying drawings, which form a part hereof, and which show specificexemplary aspects. However, examples may be implemented in manydifferent forms and should not be construed as limited to the examplesset forth herein. Accordingly, examples may take the form of a hardwareimplementation, or an entirely software implementation, or animplementation combining software and hardware aspects. The followingdetailed description is, therefore, not to be taken in a limiting sense.

FIG. 1 illustrates one example of an architecture for a system fordiscovering wireless receivers, such as Miracast receivers, according toembodiments of the present invention. Miracast is able to use thepeer-to-peer Wi-Fi Direct standard, which allows for sending up to 1080p HD video (H.264 codec) and 5.1 surround sound (AAC and AC3 areoptional codecs, mandated codec is linear pulse-code modulation—16 bits48 kHz 2 channels). The connection is created via WPS and therefore issecured with WPA2. IPv4 is used on the interne layer. On the transportlayer, TCP or UDP are used. On the application layer, the stream isinitiated and controlled via RTSP, RTP for the data transfer.

As illustrated, system 100 may include one or more client computingdevices 104 (e.g., device 104 a, device 104 b, and device 104 c)connected to one or more servers 112 over a network 110 and one morereceivers 106 (e.g., receiver 106 a, and receivers 106 b-n) that may ormay not be connected to the network 110.

In a basic configuration, the one or more client computing devices 104are personal or handheld computers having both input elements and outputelements operated by one or more users 102 (e.g., user 102 a, user 102b, and user 102 c). For example, the one or more client computingdevices 104 may include one or more of: a mobile telephone; a smartphone; a tablet; a phablet; a smart watch; a wearable computer; apersonal computer; a desktop computer; a laptop computer; a gamingdevice/computer (e.g., Xbox®); a television; and the like. This list isexemplary only and should not be considered as limiting. The computingdevices 104 may be Miracast-compatible. Any suitable client computingdevice for executing a smart discovery program (e.g., an application ordaemon) and/or remotely connecting to network 110, server 112 and/orreceivers 106 will work.

The network 110 may be a computer network such as an enterprise intranetand/or the Internet. In this regard, the network 110 may include a LocalArea Network (LAN), a Wide Area Network (WAN), the Internet, wirelessand wired transmission mediums. In further aspects, server computingdevice 112 may communicate with some components of the system via alocal network (e.g., an enterprise intranet), whereas server computingdevice 112 may communicate with other components of the system via awide area network (e.g., the Internet). In addition, the aspects andfunctionalities described herein may operate over distributed systems(e.g., cloud-computing systems), where application functionality,memory, data storage and retrieval, and various processing functions maybe operated remotely from each other over a distributed computingnetwork, such as the Internet or an intranet.

The receivers 106 are wireless and may be any device that is capable ofwirelessly receiving images, videos, and other display data from devices104 and displaying (e.g., mirroring) the display data that they receive.

The computing devices 104 may connect to receivers 106 in a variety ofways. The devices 104 may connect to receivers 106 wirelessly via Wi-Fiand/or Wi-Fi Direct. If they are Miracast compatible, they may connectdirectly to a Miracast-compatible device using Miracast over Wi-Fi as isshown by the Wi-Fi Direct dashed line 108 a between device 104 a andreceiver 106 and the Wi-Fi Direct dashed line 108 b between receivers106 b-n and device 104 b. Or clients 104 may connect to receivers 106through an access point 122 as shown by arrows 126 a and 126 b thatconnect client 104 c through access point 122 at server 112 to receiver106 b.

As illustrated by FIG. 1, a server version of a smart discovery program114 is implemented by a server computing device 112. The smart discoveryprogram 114 capable of automatically identifying the best availablewireless receiver(s) 206 for clients 104 based on a number of factorsincluding the particular user, the particular device, the current time,and the current location. As should be appreciated, the server versionof smart discovery program 114 may also be implemented in a distributedenvironment (e.g., cloud-computing environment) across a plurality ofserver computing devices (not shown). Moreover, as should beappreciated, either a client or a server version of the smart discoveryprogram may be capable of discovering the intended or best availablewireless receiver(s). While a server version of the smart discoveryprogram 114 and associated components 116-118 are shown and described,this should not be understood as limiting. Rather, a client version ofsmart discovery program 102 may similarly implement components 116-118on a client computing device 104.

The smart discovery program 114 may be implemented on a server computingdevice 112 to assist devices 104 via network 110 in discovering andconnecting to the best available receiver 106. For example, the smartdiscovery program 114 may be configured to perform methods illustratedin and described below with reference to FIGS. 5 and 6. In a basicconfiguration, server computing device 112 may include at least aprocessing unit and a system memory for executing computer-readableinstructions. In some aspects, server computing device 112 may compriseone or more server computing devices 112 in a distributed environment(e.g., cloud-computing environment).

The smart discovery program 114 may include various components fordiscovering wireless receivers for devices 104, including a location logcomponent 116 and a communication component 116. In aspects, eachcomponent may communicate and pass data between the other components.Server 112 may also include a server version of a calendar application120. These various components may be implemented using hardware,software, or a combination of hardware and software. Moreover, thevarious components may be executed on a single server computing device(e.g., server computing device 112), on multiple server computingdevices, or locally on a client computing device (e.g., client computingdevice 104).

The location log component 116 creates, searches, and maintains alocation log 130 that maps physical locations to associated receivers asdescribed with reference to FIGS. 5 and 6. The communication component118 may receive one or more communications relating to the receiver log.In aspects, communication component 114 may detect that a communicationis related to the location log component 115 based on analyzing termsused in the message (e.g., within the subject field of the message, themessage body, etc.) and/or by recognizing that attachments to themessage are related to the location log 130. As should be appreciated,communication component 114 may receive one or more communicationsrelating to a wireless receiver and/or location log by any suitablemeans. The above examples are provided for purposes of explanationshould not be considered to be limiting.

As should be appreciated, the various devices, components, etc.,described with respect to FIG. 1 are not intended to limit the systemsand methods to the particular components described. Accordingly,additional topology configurations may be used to practice the methodsand systems herein and/or some components described may be excludedwithout departing from the methods and systems disclosed herein.

FIG. 2 illustrates another exemplary architecture for a system fordiscovering wireless receivers, such as Miracast receivers, that may useMiracast over Infrastructure according to embodiments of the presentinvention. As illustrated, system 200 may include one or moreMiracast-compatible computing devices 204 (e.g., client 204 a and 204b), connected to one or more servers 230, and one or moreMiracast-compatible receivers 106 (e.g., 106 a, 106 b, and 106 c-n) overone or more networks 210.

The computing devices 204, server 230, and receivers 206 may be dividedinto logical subnets 216 (e.g., subnet 216 a, 216 b, and 216 c). Forexample, client 204 a and receiver 206 a are assigned to subnet 216 a,whereas receiver 206 b and device 104 b are assigned to subnet 216 b,and server 230 and receivers 206 c-n are assigned to subnet 216 c.

As with FIG. 1, the computing devices 204 in FIG. 2 may connect withreceivers 206 in a variety of ways including via wireless access throughwireless networks, Wi-Fi Direct (such as with Miracast over Wi-Fi), andover network 210 using Miracast over Infrastructure via 210. Forexample, computing device 204 a is in Wi-Fi Direct range (shown bydotted arrow 226) of a wireless receiver 206 b and they may discovereach other and connect via Miracast over Wi-Fi.

Additionally, all of the devices 204 in system 200 may connect to all ofthe receivers 206 in system 200 through network 210 using Miracast overInfrastructure, which may be managed by an associated application 234 onserver 230. However, Miracast over Infrastructure allows discovery ofdevices and receivers only for those elements that are located withinthe same local logical subnet. For example, computing device 204 a.Device 204 b may discover receiver 206 b but not receiver 206 a.Further, while device 204 a may connect to receivers 206 c-n overnetwork 210, device 204 a is not capable of discovering any of thereceivers 206 c-n.

The computing devices 204 may execute a client version of a smartdiscovery program 214 capable of automatically identifying the bestavailable wireless receiver(s) 206 based on a number of factorsincluding the particular user, the particular device, the current time,and the current location. Further client application 214 may practicemethods illustrated by and described with reference to FIGS. 3A, 3B, 4,and 6-8.

In some examples, the smart discovery program 214 may execute locally ona client computing device 204. In other examples, a smart discoveryprogram (e.g., a mobile app on a thin client computing device 204) mayoperate in communication (e.g., via network 210) with a correspondingserver version of smart discovery program 232 executing on one or moreserver computing devices, e.g., server computing device 230. In stillother aspects, rather than executing a client version of a smartdiscovery program, the one or more client computing devices 204 mayremotely access, e.g., via a browser over network 210, the smartdiscovery program 232 implemented on the server computing device 230, ormultiple server computing devices (e.g., in a distributed computingenvironment such as a cloud-computing environment). In aspects, thesmart discovery program, whether executed on a client, a server, or in acloud-computing environment, may be integrated into an operating systemor the like.

The computing device 204 may also access content from a server device230 that may be stored in different communication channels or otherstorage types. For example, various documents and content may be storedusing a directory service 238, a web portal 240, a mailbox service 242,an instant messaging store 244, or a calendar service 246. The smartdiscovery program 214 may be employed by a client that communicates withserver device 230 and/or the smart discovery program 232 may be employedby server device 230. The server device 230 may provide data to and froma client computing device 204 through a network 210. Any of theseembodiments of the computing devices may obtain content from the store236.

As should be appreciated, FIG. 2 is described for purposes ofillustrating the present methods and systems and is not intended tolimit the disclosure to a particular sequence of steps or a particularcombination of hardware or software components.

Automatic Discovery of the Correct Wireless Receiver for a ScheduledAppointment

FIGS. 3A, 3B, 4-6 illustrate various methods for automaticallydiscovering the correct wireless receiver for a scheduled appointment inaccordance with embodiments of the present invention. These methodsinvolve user devices and receivers that may be, but do not have to be,Miracast-compatible. As should be appreciated, FIGS. 3A, 3B, and 4-6 aredescribed for purposes of illustrating the present methods and systemsand are not intended to limit the disclosure to a particular sequence ofsteps or a particular combination of hardware or software components.

FIGS. 3A and 3B illustrate exemplary methods 300 and 330 performed at auser device (such as computing devices 104 in FIG. 1 and devices 204 inFIG. 2) for automatically discovering the correct wireless receiver(such as receivers 106 in FIGS. 1 and 206 in FIG. 2) in a location wherean appointment (such as a meeting) is scheduled. These methods may beperformed by the smart discovery program 214, and more particularly bythe smart meeting component 218, in conjunction with calendarapplication 214 on device 204 a in FIG. 2 and/or calendar service 246.The user device (e.g., the discovering device) and the wireless receivermay be, but do not have to be, Miracast-compatible.

In FIG. 3A, method 300 automatically discovers the appropriate wirelessreceiver for an appointment, meeting, or other calendar event for a userwho is associated with a user device. Method 300 may begin at eitherstep 302 or step 304. If the method begins at operation 302, it moves tooperation 306 where it determines whether the user has a meeting at thecurrent time. This may be determined by a calendar application (such ascalendar application 214 and/or calendar service 246) and/or by ameeting component 218 of the smart discovery program 214. The calendarapplication may determine a current time and compare the current time toentries within a user's calendar for the current time. In aspects, thesystem further considers not only meetings that overlap the currenttime, but also meetings that fall within a certain window (such as 15minutes) of the current time. If the user does not have a meetingscheduled (“NO” at 306), method 300 terminates at step 310. If, on theother hand, there is a meeting that is happening or is about to happen(“YES” at 306), the method proceeds to operation 308.

Method 300 may also begin at step 304 when the smart meeting applicationreceives a notification that an appointment or meeting has started or isgoing to start soon. The user device may have a calendar or schedulingapplication that keeps track of meetings, appointments, and othercalendar objects, such as calendar application 214 of user device 204 ain FIG. 2 that may work in conjunction with calendar service 246 in FIG.2. If so, method proceeds to operation 308.

At operation 308, method 300 retrieves the location for the appointment.In aspects, the smart discovery program may retrieve this informationfrom a calendar application or the calendar application may send themeeting location with the notice that a meeting is starting or about tostart. In another embodiment, the meeting location may be contained inan invitation for the meeting. In aspects, if the location for themeeting cannot be retrieved, the method proceeds to step 336 of FIG. 3B.

Next, method 300 determines whether the meeting location has anassociated receiver in a location log. In aspects, the smart discoveryprogram may make this determination by looking up the locationidentifier learned from step 308 to see if there is an entry in alocation log for that location, and if so by retrieving the receiver IDthat is associated with that location in the log. The location log maybe stored locally on a computing device, such as in local receiver log212 on computing device 204 a, and/or stored at a server, such aslocation log 130 in store 128 for server 112 in FIG. 1. If there is noentry for the location in a location log or if the entry is present butdoes not include an associated receiver (“NO” at 312), method 300identifies available receivers or relevant receivers using the methodshown in FIG. 7 in step 315 and then attempts to find a partial matchbetween the meeting location name and the receiver name in step 317. Ifit finds a partial match (“YES” at 317), the method proceeds to step314. If not (“NO” at 317), the method terminates at 310. If, on theother hand, the log includes an entry for the location and identifies amatching receiver (“YES” at 312), method 300 moves to operation 314.

At 314, method 300 determines whether the user device is receiving asignal from the matching receiver. If method 300 determines that theuser device is not receiving a signal from the matching receiver (“NO”at 314), it proceeds to step 316 where it periodically checks to see ifthe Matching Receiver becomes available.

If it is receiving a signal (“YES” at 314), the user device prompts theuser to connect to the matching receiver at step 318. The prompt may bein a format that notifies the user that there is a matching receiver forthe appointment in question. The prompt may also include an option forthe user to select to be connected to the matching wireless receiver toshare the information presented on the user device with the matchingreceiver. If the user chooses to connect (“YES” at 322), the user deviceis connected to the wireless receiver at step 324. Method 300 thenterminates at step 326, where the matching receiver may be logged asillustrated in FIG. 5. If the user chooses not to connect (“NO” at 322),method 300 moves to step 320 where the matching receiver is stored in alocal receiver log, such as log 212 in FIG. 2, for the duration of themeeting so that the user may easily connect to share the user devicescreens later in the meeting, if desired.

FIG. 3B illustrates another exemplary method 330 for automaticallydiscovering the right wireless receiver for an appointment, meeting, orother calendar event for a user who is associated with a user device. Itbegins at step 332 where the user device has received a request from auser to share the device screen with a wireless receiver. At step 334,method 330 determines whether the user has a meeting at the currenttime. This may be determined by a calendar application and/or by ameeting component of the smart discovery program as discussed in moredetail with regard to FIG. 3A. If the user does not have a meetingscheduled (“NO” at 334), method 330 terminates at 336 where it may beginmethod 700 for identifying the most relevant receivers in accordancewith an embodiment of the present invention.

If the user does have a current meeting or has a meeting that is aboutto begin (“YES” at 334), the method proceeds to operation 338. Atoperation 338, method 330 determines whether the location for theappointment is available. If the location is not available, method 330proceeds to step 339 where it periodically checks to see if the locationhas become available. In an alternative aspect, if the location of themeeting is not available at step 338, the method proceeds to step 336.If the location of the meeting is available (“YES” at 338), step 340determines whether the meeting location has a matching receiver IDthrough a process which is shown in more detail in FIG. 6.

FIG. 6 illustrates a method 600 for determining whether a meeting has amatching receiver in accordance with embodiments of the presentinvention. Method 600 may be performed by a client version of the smartdiscovery program on a computing device, such as devices 104 of FIG. 1and devices 204 of FIG. 2, and/or by a server version of thisapplication on a server, such as server 112 in FIG. 1 and server 230 inFIG. 2. At step 604, the smart discovery program consults a location logto determine whether there is an entry that matches the location for theappointment. It may retrieve this information from a local log, such aslocal receiver log 212 on computing device 204 a in FIG. 2, or from aserver log, such as location log 130 in store 128 for server 112 inFIG. 1. Either way, if the appointment location has an entry in a logand the entry contains an associated receiver (“YES” at 604), the methodproceeds to step 606 where the matching receiver ID is retrieved fromthe location log. Method 600 terminates at step 614, where it may returnan answer of “YES” to step 340 of FIG. 3B.

If the location does not have an entry in a location log or there is nomatching receiver for that location in the log (“NO” at 604), adetermination is made as to whether the location name or identifier forthe appointment matches a name from a list of receivers at step 608. Thelist of receivers may include all wireless receivers that are withinWi-Fi range of the user device, or all wireless receivers that arewithin the same local subnet as the user device (using Miracast overInfrastructure), or all relevant receivers that may be obtained throughan embodiment of the present invention illustrated in FIG. 7. Step 608compares the location identifier with the receiver identifier to see ifthey at least partially match. For example, if a meeting location is aconference named “27/2705”, the system will search the list of receiversto see if any receiver ID's at least partially match the locationidentifier. If one of the receivers has and ID “2705”, a stringcomparison would consider this to be a match and retrieve the receiverID. If there is a match (“YES” at 608), method 330 moves to step 606where it selects the matching receiver and retrieves the matchingreceiver ID at step 606. Method 600 terminates at step 614, where it mayreturn an answer of “YES” to step 340 of FIG. 3B.

If the location identifier does not match any of the identifiers for anyof the receivers on the list of receivers (“NO” at 608), method 600concludes that the appointment location does not have a matchingreceiver at step 610 and terminates at step 612 where it returns ananswer of “NO” at step 340 of FIG. 3B.

Returning to FIG. 3B, if there is not a matching receiver (“NO” at 340),method 330 terminates at 336 where it may begin method 700 foridentifying relevant receivers in accordance with an embodiment of thepresent invention. If there is a matching receiver (“YES” at 340),method 330 then proceeds to step 314 of FIG. 3A as described above withreference to steps 314-326 of FIG. 3A.

FIG. 4 illustrates a method 400 for logging matching receivers andlocations by a computing device in accordance with an embodiment of thepresent invention. Method 400 may be performed by the smart discoveryprogram 214, and more particularly by the logging component 220 of thisapplication on device 204 a in FIG. 2. Method 400 begins at step 402when a user device connects to a wireless receiver. At step 404, thesmart discovery program determines whether the ID for the connectedreceiver is stored in a local receiver log, such as log 212 in FIG. 2,of the user device. If there is not an entry in the local log (“NO” at404), the connected receiver ID is stored at step 406 and the methodmoves to step 408. If there is an entry for the connected receiver inthe local log (“YES”) at 404, the method moves to step 408.

At step 408, method 400 determines whether there is a locationassociated with the connected receiver. For example, if the systemdetermined that the connected receiver has a name that at leastpartially matches the name of the location, for example as describedwith reference to step 608 of FIG. 6, then the receiver does have anassociated location (“YES” at 408). At step 410, the receiver ID andassociated location are sent to the server to be stored in a serverlocation log, such as log 130 in FIG. 1, and the method terminates at412. If there is not an associated location, method 400 terminates at412.

FIG. 5 illustrates another method 500 for logging matching receivers andlocations by a server in accordance with an embodiment of the presentinvention. Method 500 may be performed by the server version of thesmart discovery program 114, and more particularly by the location logcomponent 116 of this application on server 112 in FIG. 1.

Method 500 begins at step 502 where the server receives a receiver IDand associated location ID from a user device, such as that shown bystep 410 of FIG. 4. At step 504, the server determines whether thereceiver ID has already been stored in the server location log, such aslog 130 in FIG. 1. If so (“YES” at 504), the method proceeds to step 506where it determines whether the location that is associated with thisreceiver ID in the log matches the location received from the userdevice. If so (“YES” at 506), method 500 ends at 512. If the locationthat is associated with this receiver ID in the log does not match thelocation received from the user device, the entry for this receiver inthe log may be updated to match the information received from the userdevice at step 510. In another embodiment, the system may not update thelocation log but rather keep the information as stored in the serverlog.

If there is no entry in the server log for the receiver ID (“NO” at504), a new entry is created for the receiver ID and the associatedlocation in the server log at step 508. The method ends at 512.

Smart Discovery of Wireless Receivers for Miracast over Infrastructure

FIGS. 7-8 illustrate various ways to automatic discover relevantwireless receivers within a system that uses Miracast overInfrastructure, such as system 200 in FIG. 2. As should be appreciated,FIGS. 7-8 are described for purposes of illustrating the present methodsand systems and are not intended to limit the disclosure to a particularsequence of steps or a particular combination of hardware or softwarecomponents.

Method 700 in FIG. 7 may begin in a number of ways. In an embodiment,when a device receives a user request to connect to a wireless receiver,the smart discovery program may run through method 330 to determinewhether the user has an upcoming or ongoing appointment. If there is noappointment (“NO” at 334 of FIG. 3B), method 700 may begin at step 704.In another embodiment, method 700 may begin at step 702 withoutperforming method 330 when a user request to connect is received. In yetanother embodiment, method 700 may begin at step 706 when a user requestto connect is received and the user has elected not to connect to anyreceiver included in a local receiver log as described below withreference to FIG. 8.

Regardless of which way method 700 begins, step 708 determines a currentlocation of the user device. Step 708 may be performed by the locationcomponent 216 of the client version of the smart discovery program 214.Current location may be determined in a number of ways based on avariety of sources including without limitation a GPS signal from asensor in the user device, the identity of a wireless network that theuser device may be connected to, self-reported location information froma user, the IP address being used by the user device, a location of acell tower the user device is connected to, a list of currently visibleWi-Fi networks, and any other means of determining location of a userdevice.

Step 710 sends an mDNS broadcast (e.g., IP multicast) query whosepurpose is to identify a list of all Miracast-compatible receiverswithin the local logical subnet with the user device. The mDNS querywill include a question that asks all Miracast-compatible receiverswithin the same local subnet to identify themselves. The multicast queryincludes the device's IP address so that appropriate receivers mayrespond to the query. The query also contains a query ID. In alternateaspects, step 710 may be omitted if the device has recently issued anequivalent query and it has cached the results it received in responseto this query. Cached results can be used if recent enough and if thesource device has not changed its location.

At step 712, each receiver that receives the mDNS query and can answerthe question contained therein in the affirmative will respond with amDNS response to the user device that sent the mDNS broadcast query. Inaccordance with the present invention, each mDNS response will alsoinclude a hint that contains location information (whether GPS, LDAP, orsomething else) about the location of the receiver in the payload of themDNS response. The mDNS response also includes the query ID so that thecomputing device may match the response to the query.

Step 714 determines whether the current location of the user device fromstep 708 matches or is close to the location hint in the mDNS responsefrom the responding receiver. Location matching can be performed indifferent ways depending on the type of location information in theresponse. For example, if the location hint contains physicalcoordinates (GPS) then the proximity/location matching will be performedby verifying that the source device's position is within a certainradius/distance/range of the coordinates of the receiver in theresponse. As another example, if the location hint in the responsecontains building/floor/room information, proximity/location matchingcan be determined by matching building and floor, depending ongranularity/resolution of the returned data. That is, if the returnedreceiver's location contains only building information,location-matching may be determined by just matching the building wherethe source device (projecting device) is located. If the responsecontains building and floor data, proximity can be determined bymatching both building and floor. The proximity/location matchingdecision is also influenced by the kind of location informationavailable on the source/projecting device. For instance, the receivermay include GPS location but the source device may not have GPS, and itmay be able to get location info only in less reliable ways (e.g.visible wi-fi networks) or only by building/floor location. Furthermore,the location matching decision may account for the level of accuracy(margin of error) of location data on both sides. cIn aspects, thelocation hint may include an estimate of the accuracy of the locationdata itself (e.g. “within X meters”). The location-matching decision mayfactor in this estimate. For example, if a radius/distance/range is 100meters and the and two devices are 150 meters away from each other, thesystem would not decide that a receiver is out of range if one of thetwo locations/positions is given with an accuracy of “within 50 meters”or worse.

Step 714 may be performed by the location component 216 of the smartmeeting application 214. If the responding receiver's location hintmatches the device's current location (“YES” at 714), the receiver isadded to a list of relevant receivers at step 716. If not (“NO” at 720),the receiver is not added to the list and/or the response is ignored ordiscarded at step 720. Either way, method 700 proceeds to step 718 whereit determines whether it has received any other mDNS responses. If so,it retrieves the next response and proceeds to step 714 where itdetermines, based on location, whether the next receiver should be addedto the list of relevant receivers. In this way, the smart discoveryprogram reviews all of the mDNS responses from all the receivers'location in the same subnet and produces a list of only those receiversthat are within a close proximity to the user device. Method 700 ends atstep 724 where is provides a list of relevant receivers, where therelevant receivers are both available for connection and located inclose proximity to the user device.

FIG. 8 illustrates an exemplary embodiment of a method 800 foridentifying available Miracast-compatible wireless receivers,particularly those that are located within a different subnet from theuser device. At step 800, the system (e.g., smart discovery program 214)receives a request to connect to a wireless receiver. Next step 804retrieves a list of receivers from the local receiver log (such as log212), which may include all Miracast-compatible receivers that thedevice has previously connected to. In aspects, these receivers werelogged as part of step 406 in FIG. 4. The list of receivers is presentedto the user. If the system receives a selection from the user to connectto one of the listed receivers at step 806, method 800 proceeds to step808 where the user device connects to the selected receiver. If thedevice does not receive a selection to connect at step 806, method 800moves to step 810 where it retrieves a list of receivers from a locationother than the local receiver log. The other receivers may include allwireless receivers that are within Wi-Fi range of the user device, orall wireless receivers that are within the same local subnet as the userdevice (using Miracast over Infrastructure), or all relevant receiversthat may be obtained through an embodiment of the present inventionillustrated in FIG. 7.
